Crystals are modeled as discrete lattices, generated by a list of independent finite translations (Coxeter 1989). Because discreteness requires that the spacings between lattice points have a lower bound, the group of rotational symmetries of the lattice at any point must be a finite group (alternatively, the point is the only system allowing ...
[1] [2] The 2005 NASA Authorization Act designated the American segment of the International Space Station as a national laboratory with the goal of increasing the use of the ISS by other federal agencies and the private sector. [3] Research on the ISS improves knowledge about the effects of long-term space exposure on the human body.
The Laue equations can be written as = = as the condition of elastic wave scattering by a crystal lattice, where is the scattering vector, , are incoming and outgoing wave vectors (to the crystal and from the crystal, by scattering), and is a crystal reciprocal lattice vector.

In 2006, NASA studied alternative ways of delivering AMS-02 to the space station, but they all proved to be too expensive. [33] In May 2008, a bill [34] was proposed to launch AMS-02 to the ISS on an additional shuttle flight in 2010 or 2011. [35] The bill was passed by the full U.S. House of Representatives on June 11, 2008. [36]

Made In Space Europe will work on the development of a low-cost modular robotic arm for in-space applications. [8] On 17 January 2020, Florida governor Ron DeSantis announced the company's corporate headquarters would be relocating from Mountain View, California to Jacksonville, Florida. The headquarters relocation and expansion effort will ...
